I received my first summary mail already, and it brings my first feature request:

I'd like to receive only reports for the newest version of a module on CPAN.

I often upload a new version of a module to fix failures that the CPAN testers reported (thanks for that), and then two weeks later I still get FAIL reports for them, which is both annoying and distracting.

(If the majority of authors wants to receive reports for old modules that could perhaps be made configurable).

Already planned. This has been a quick response to an avalanche of resistance to all the reports some authors were getting. The first phase was to reduce the flood to at most one mail a day, the next phase is to fine tune the defaults and then finally we plan to open up the preferences to authors to choose their own settings.
